rfolication filed May 17, 1G05. Serial No. 250,761,

Ee it known that l., citizen of Athe United ites, residing at Cainw bridge, in the county ci Suilolk and State ol" ilflassachnsetts, have invented an improve ment in Machii es tor Making; innersoles, oi which the following description, in connection with the accompanying drawings, is a specilication, like numerals on the drawings representing like pe '-ts.

lviy invention applies to that kind ol innersolc in which a stitch-receiving lip is iornnd. by cutting in horizontally along the periphery of the innersole-body, so as to iorin a thin lip above the leather-edge, and by i'orining a similar cooperating lip by cutting obliquely dowi'rnfardly and outwardly along lhe inside of the first-mentioned lip, said two lips being then turned up vertically and secured together to form an upstanding` stitch-receivin lip or ridge.

-n making innersoles the leather is 'lirst moistened' to in se it less refractory, so that the lip can be tin'ned up, and in making the above kind of innersole the entire top surface is smeared with rubber cement, which. is allow'edto stand until the cement has dried, (as it will not hold while any naphtha remains.) Then after the two lips have been turned up and hammered together (this being the manner of securing the cemented lips) the Whole surface is again cemented in order to coat the recently-eut leather surface. Not only is an undue amount of cement used and much time consumed, but as the cement dries the moisture escapes from thc leather also, which stili'cns and will therefore not y stay turned up. Accordingly I have devis-'ed the hereinaiter-described mechanism for obviat ing the foregoing' disadvantages, my mechanism producing a clean neat job without Waste oi cement and permitting the lip to be turned up at once and secured While freshly moistened and pliable. My invention makes this kind of innersole as practical and advantageous asthe so-called Gein innersole.

in the accompanying drawings, in which l have illustrated sullicient details ot a inachine to make my invention understood, Fig- ANDREW Thema, a l

knives, cement-delivery apparatus, and ad; jacent parts to the innersole, a fragmentary view of the latter being indicated.

(ln a suitable rotary standard l, herein shown as continuously rotated b v a drivingnfheel i2 and adapted to be raised and low ered by a toot-lever 3 against the action of a spring; 4, i: a table 5, norinall)vv rotating' in the direction oli the arrow tor supporting` the innersolo to he treated. Above this Worktalile is a li oder or 'plunger (l, whose carryinglrain. slides longitiulinall)Y in the main l'ranie A oi" the n'iachine, beingy normally retracted by a spring 7, said feeder havinga serrated lower end to engage thc Work and rapidly reciprooated .by any suitable nien-ns,

as a cani l5, oi'ierating in opposition to a spring 9. Adjacent this feeder is a verticallystationary rest l() for holdingr the Work down upon the table as it is led to opposite ormers l] 12, herein shown as knives, whose forward edges 12; i4 separate the lips l5 16 from the innersole-body 17, said lips being turned upwar ll'y toward each other by properlycurved shaping;` portions 18 19 at the rear of the iront edges i3 14 of said iormers or shapers. When the lips have been brought substantially together, they are rapidly pounded by a vibrating hammer or beater 2l), whivh operates against the lip 15, While the opposite side ofthe lip 16 is engaged by a stationary anvil or beater 21. 2() is operated by any suitable means, as by a cam 22 on the shaft against the action of a spring 24. i. have not attempted to show the vforegoing mechanism in elaborate detail, but have merely indicated sul licient portions thereof to represent the general operation and construction, my invention being: intended to, l-)perate with a machine of this general' character, (for instance, such as shown 1n Patent No. 656,842, of August 2S, 1900.)

As bel-oro stated, my invention resides in providing means for making; it possible to do away with the cost and delay of the cementing operations, as above explained, and l accomplish this` by interposing between the iormers li. l2 ,and beaters 2() 2l means for locally coating` the inner surfaces of the lips with a quick-drying' hot .cement capable of adhering tenaciously to leather Without first required to dry and set. rthis may be accomplished by various devices and means; but prei/fer to .employ a small Wedge-shaped roller or disk 25, onrnaled at 26am the lower 'lhe vibrator end of a cement-delivery spout, 27, leading.

from a eetnent-t-anh 28, heated by any suitl able inea-ns, as by steam-pipes2t). 'lhe llow t ol" rement may be further regulated by a' valve 30. The lormers Il t2 are spat-ed` apart so that they do not quite elose the ehant'tel ol the li i Aformed by the two lips 15 lt, and as the so e led along by the table 5 tlte roller 5 deposits in said eha'nnel just tlte right amount ol" ltot eement for properly coating the eont iguous walls ol the lips, whieh are therettpon immediatehelosed and pouttded together by the beatin'g aetion `tt'the eooperating parts 2t) l. Suitable pulleys 3| 32.33 and a belt 2S-l serve to drive the Ina,- chine.

My invention makes it possible to unite the channel-lips wltile damp or wet, and henee more easily shaped aml more readily` ttnited. lt` also enablesl the innersolelto be made with extreme tteatttess, avoiditlg thel prol'use smearing ol the ittttersole with the disagreeable and expensive rubbereement heretofore ttsed. lt also perntits tlte innersole to be eompletedat onee. l employ a rement eontposed mainly ot" gutta-perehat and gutn ehielde or pontianae, tor any resinotts gtttn tempered to ehill quieldy.) which will ehill and set almost instantlyttpon eomintl'in eontaet with tlte eold wet surl'aee olnthe lip-eltannel. My meehanisn delivers ottly the stnall quantity ol' eoating neeessary l'or liornting an adhesive tnedittttt between the] eontiguous walls oll theleatltet' lips, :ttul just belore the eetnent has had a eltauee to set said walls are l`oreibly hammered tt'tgether.

'lhe loot' is then released l't'ont the treadle. permitting I he eoustant ly-rotat ing table 5 to; engage the uttder side oll tlte innersole` i wltereupolt the rapidly-reeiproeatittg aetion ol` tlte serrated l'eeder tt intertniltingly presses theinnersole ltard ttpon said moving table and releases said pressure. tlte result being a eonstant l'orward lerding ol the innersole, whieh is held in plaee by the rest lt). whereupon the lips l5 tti are lot-med and lil'ted upward by tlte lormer or sltaper knives ll l2 and are thereupon inintedi.-ttel v l eoated by the small atnount o|- hot eentent delivered thereto by the stnall disl\' 25. whielt rolls along the bottom ol tlte eltannel l'ornted by said upturn'ed lips. .\s the 'rement smeared upon the walls o`l` tlte ehannel it begins innnediatel)l to ehill .ttul 'set: but said walls are instantly brought together behind the wheel attd l`oteibly stueh against `aeh other by tlte beatels 2021, theteby entirely l eompletingthestiteh-reeeivinglip,sothat'tlte innersole travels l'orwat'd in its linished and permanent shape ready to reeeiv t a rein loreing-eove.rit tg, il desired, or to be. used direet ly in shoe tnanulaet'ure.`

l prel'er to employ a roller 25 lor-delivering tlte tjttielt-ehilling hot eentent, as its engagement with the bottom of the lip-channel eauses it totdeliver' the cement toward the wider port iott otl said channel and the wedgeshapett sides ol said disk aid in properly distribtn ing the eement uniformly over the contiguous walls ol said channel; but I wish it understood that l am not limited to this'eonst rue't ion. as my invention includes, broadly, any means lor simultaneously turning up the lips and depositing eementitiotts material therebetween j ust as `the lips are being brought linally together.
